Discovery of 5-substituted-N-arylpyridazinones as inhibitors of p38 MAP kinase.

Abstract:

:The synthesis, structure-activity relationship and modeling of a series of 5-substituted-N-aryl pyridazinone based p38alpha inhibitors are described. In comparing the series to the similar N-aryl pyridinone series, it was found that the pyridazinones maintained a weaker interaction to the p38 enzyme, and therefore showed generally weaker binding than the pyridinones.
